WE'RE still waiting for our invite.

Katy Perry has been busy promoting her movie Part Of Me 3Dwith astring of surprise screenings here in London and across the pond.
Russell Brand's ex took to Twitter to share snaps of the latest surprise events in London and L.A but has been leaving us guessing as to where the next screening will take place.

Along with the London pic, Katy commented: "Had tons o' fun in London today at a surprise screeningWish I could sit w/ all of u when u see #KP3D".

And we have to point out, Katy somehow managed to make her 3D glasses actually look HOT. How, please?

The One That Got Away songstress looked gorgeous last night in L.A. and it seems her wardrobe has recently been determined by the weather.

Now back in sunny L.A., Katy opted for a mor! e colour ful outfit than those she's recently been spotted wearing during her visit to rainy England.

The singer's pretty red print dress was given an edgy flair with the addition of her trusty leather jacket and a pair of AMAZE red wedges (we WANT).

We cannot wait to see the movie (just as soon as we find out how Katy made those funny glasses look good).
